SPECIFICATION forming part of Letters Patent No. 443,176, dated December 23, 1890. Application filed August 30, 1890l Serial No. 363,465. (No model.)

.To all whom t may concern:

Be. it known that I, JOHN G.GILMER, a citizen of the United States, residing` at. Oxford, in the county of Sumter and State of Florida, have invented a newv and usefulGraiu-Binder, of which the following is a specification.

This invention has relation to grain-binder attachments for harvesters, and relates to that class thereof in which the band is formed from the gavel-in other words, from the grain itself during the operation of building the bundle.

The objects and advantages of the invention, together with the novel features thereof, will hereinafter appear, and the latter particularly pointed out in the claims.

Referringto the drawings, Figure l is a plan of abinder attachment constructed in accordance with myimprovement. Fig. 2 is a similar view, the platform removed. Fig. 3 is a longitudinal vertical section. Fig. 4 is a sin1ilar View, the tucker being in the act of tucking. Fig. 5 is atransverse section looking toward the twister. Fig. 6 is a transverse sec tion in the opposite direction. Fig. 7 is a side elevation. Fig. 8 is a detail in perspective of the clamping-arms and their shaft and support. Fig. 0 is a perspective of the tucker. Fig. 10 is a longitudinal section of the twister. Fig. 11 is a detail in elevation of the cam-pulley operating the elamping-arms- Like numerals of reference indicate like parts.

In practicing my invention l locate the mechanism hereinafter `described in an oblong frame consisting of opposite front and rear side bars l, connecting end bars 2, and a central longitudinal bar 3, said frame being suitably supported in the usual manner and as will be readily apparent to those skilled in the art.- In transversely-opposite bearings 4, located upon the under side of the rear side bars and the central bar, there is journaled the main power-shaft 5, which extends beyond the rear bearing and is there provided with the toothed gear G. periphery toothed only for about two-thirds its length, the remaining portion being plain or untoothed, as at 7. Beyond the gear 6 a pulley 7 is mounted upon said shaft, which pulley receives motion from the operating The gear 6 has its` mechanism of thebinder. Between its bearings the shaft 5 is provided with a cam-pulley 8, provided with a cam pin or lug i), extending frorn the inner face of the same.

Upon a headed lug 10, extending from the inner face of the adjacent side bar 1, th-ereis loosely mounted a er-arm 11, slotted longitudinally at its rear end, as at 12, whereby it is adapted for both a pivotal and reeipro` cal movementupon the stud 10. The tuckerarm is laterally and inwardly bent to pass inside of the cam S, and upon its underside opposite the cam is provided with a cam-recess 13, which Vterminates at its inner end in an abrupt shoulder lic. Beyond the cam-recess t-he tueker-arm is horizontally and then upwardly bent or disposed and terminates in a tucking-nger 15. At one side of the shaft 5 there is journaled in bearing 1G a counter-shaft 17, the ends of which extend beyond the bearings, and at its outer end is provided with a small pinion 1S, adapted to be intermittently operated by the gear 6, andat its inner end is provided with a small beveled pinion 19.

In longitudinally-opposite bearings 20, secured to the under side of the opposite end bars near the front of the framework, is a longitudinal shaft 2l, the ends of the shaft extending beyond the bearings and providedv at one end with a gear 22 and at the 'opposite end with similar gear 23. lVithin its bearings and nearly opposite the shaft 17 there is mounted upon the shaft2l a beveled pinion 24, which engages and is driven by the pinion 19. Near the opposite bearing there is located a sprocket-wheel 25.

In one of the end bars of the frame-work there is seated a journal or bearing .26, in which is mounted one end of a stub-shaft 27, the opposite end being journaled ina bracket 2S, secured to the frame-work. Between its bearings the shaft carries a small pinion 29, which is engaged and driven by a large pinion 30, in turn engaged and drivenby the gear or pinion 22. Upon the inner end of the stub` shaft there is secured a hollow tube 31, spirally slotted from end to end, as at 32, and terminating in the slightly outward bent finger 33.

34. designates an outer hollow tube which ICO surrounds and loosely tits the tube 31, and said tube 34 isspirally slotted, as at 35, in the direction opposite to the slot The outer tube 34 is stationary, while the inner tube 3l is adapted to revolve, and the former-mentioned tube is supported by a bracket 36, secured to the end bar of the binder. Each of these tubes forms what I term a twister-section, and the two combine to form the bandforming twister, which terminates at one side of and directly over the l ing-finger heretofore mentioned.

37 designates a standard provided at its upper end with a bearing and mounted upon the end bar of the framework opposite the one upon which is mounted the twister. In this standard is journaled a short shaft 3S, the ends of the shaft extending beyond the bearing and its outer end supported by a bearing-bracket 39, secured to the end bar of the frame-work. A gear 4() is mounted upon the shaft between its two bearings, which gear is engaged and driven by a large gear 4l, mounted upon the shaft 42 and driven by the gear 23. Upon the inner end of the shaft 38 is mounted a sprocket-gear 43, which by a chain 44 is connected with and driven bythe small sprocket 25. At one side of the sprocket, and in this instance formed integral therewith, is a cam-wheel 4G, having a cut-away portion 47, as shown.

43 designates a crank or L-shaped arm, also mounted upon the shaft 38, and is provided at opposite ends with bearings 4f), in which is journaled a rock-shaft 50. The rockshaft 50 extends beyond its bearings, and at its-outer end is provided with a cam-arm 51, maintained in contact with the surfaceof the cam-wheel 47 by means of a coiled spring 52, which encircles the rock-shaft and has one end secured thereto and to the crank-arm. The inner end of the rock-shaft has fixed thereupon a curved gavel-clamping arm 53, and at one side of the shaft there is rigidly secured to the crank-arm a com panon gavelgripping arm 54.

55 designates the platform which covers that portion of the framework unoccupied by the twister, the gavel-gripping arms, and the crank-arm, said platform being provided with a slot 56 at its inner edge for the passage of the crank-arm and with an opening 57 for the sprocket-chain 44.

58 designates a bracket secured to the under side of one of the side rails7 and to the same is secured one end of a coiled spring 59, the opposite end of which is secured to the rear end of the tucker-arm, whereby said arm is spring-pressed toward the opposite end of the machine, or, in other words, toward the twistingV mechanism.

This being the construction, the operation is as follows: Beginning with the time that a sheaf is formed, the grippingarm, by the ac. tion of the cam-arm upon the cam 46 and by reason of said cam-arm coming opposite the cam portion 47 of the cam-wheel, is opened and the sheaf dropped down outside of the frame. main open, while bythe `gear described the L- shaped arm is revolved, and they remain open during a half-revolution until brought to the platform upon which the grain from the harvester is thrown and is caught by said clamping-arms. After taking up the gavel from the platform the arms, by the action of the cam, are closed, and the revolution is continued until the gavel has been carried one and a half time around the twisting mechanism, which, it will be understood, is rapidly revolving. As said mechanism revolves it takes from the' gave'l a continuous series of grain, which is rapidly twisted into a band, as will be apparent. By this time the open space of the gear (i is opposite the small pinion 18, and the drive-wheel passes on without producing any further revolution. The lug 9 has now arrived in contact with theI cam-recess ot' the tucker-arm, and iirst raises the arm, forcing the finger against the band and forcing the band into the sheaf or gavel.

A continuous movement of the lug brings it in contact with the shoulder at the end of thecam-recess and so reciprocates the erarm that .the tucking-iinger is forced lengthwise the gavel, and thus the band is tucked under that port-ion which encircles the gavel. As the lug passes beyond the. shoulder and the tucker-arin ceases to be furtherinfluenced by the lug, the coiled spring returns the tucker-arm quickly to its original position. At this moment the teeth of the gear 6 re-.engage the pinion, and the operation again com.- mences. As the mechanism is started, the clamp-arms reopen and discharge t-he gavel, now a sheaf complete, and said arms come around to take a fresh supply of grain. The cam upon the end of the arm is a loose cam, and is so geared that the cam portion thereof 47 comes opposite the cam-arm of the rock-arm at every alternate revolution of the clampingarms. ltwill thus be seen that one and onehalf revolution of the crank-arm is necessary to place the band around the gavel, and when the clamping-arms are stationary the tucking mechanism begins. The band is made by t-he t'wisters,'wl1ich are rotated under the gavel as said gavel travels in a circularpath, the bent or curved point 33 of the inner twisting-section taking up a few strands of straw at each revolution and rapidly forming the same into a band subsequently drawn out from the twisters by the revolution of the gavel.

In a grain-binder attachment, the combination, with the gavel-carrying arms, of the band-twisting mechanism consisting of a iixed. and movable tubular section, one mounted within the other and each spirally slotted in` a direction opposite to that of the other, and means for rotating said movable sectiomsubstantially as specified.
